Singapore’s stock-market rally has created an unusual problem for investors.

The Straits Times Index has reached record territory, but much of the market has not participated.

The three major banks and Singapore Exchange have accounted for roughly 95 per cent of the STI’s gains year to date, according to DBS Group Research.

That statistic reveals something more important than whether the STI is “expensive”.

The real risk is concentration.

When a small number of heavyweight stocks do most of the lifting, the index can continue rising even while a large part of the market remains stagnant.

Eventually, investors begin asking a different question:

Where is the next source of returns?

That could create an important opportunity in Singapore’s neglected property companies, REITs, mid-cap stocks and companies with identifiable catalysts capable of unlocking dormant value.

But investors should not interpret this as a simple “sell banks, buy everything else” trade.

The more interesting thesis is that Singapore’s market may be moving from a liquidity-and-dividend-driven phase into an earnings-and-catalyst-driven phase.

That could produce a very different set of winners during the remainder of 2026.

The STI’s biggest weakness may be hidden beneath its strength

A rising index normally signals broad investor confidence.

This rally is different.

If most of the index’s gains are being generated by banks and SGX, the headline STI performance tells investors relatively little about the health of the broader market.

This creates a phenomenon familiar in concentrated markets:

index strength can coexist with stock-picking opportunity.

The banks have benefited from several powerful forces.

They have strong balance sheets, high dividends and attractive profitability.

But their share prices have also risen significantly.

As valuations expand, each additional dollar of earnings growth becomes less valuable to the shareholder unless earnings can accelerate sufficiently to justify the higher multiple.

That is where the mathematics of investment changes.

A bank can remain an excellent business while becoming a less attractive stock.

The next phase may reward catalysts rather than quality alone

For much of the recent rally, investors could justify buying Singapore banks on a relatively straightforward thesis:

high-quality franchises + strong capital positions + dividends + resilient earnings.

But as valuations rise, investors need something extra.

They need a catalyst.

That is why value-unlocking stories become more interesting.

A company trading below the market value of its underlying assets does not necessarily remain undervalued forever.

Something needs to change.

That catalyst could be:

• an asset sale;
• a property redevelopment;
• a restructuring;
• a spin-off;
• a special dividend;
• a strategic investment;
• a change in capital allocation;
• or simply management demonstrating that the market is valuing the business incorrectly.

This is a fundamentally different investment approach from buying a high-quality compounder and waiting.

It is closer to catalyst-driven value investing.

Singapore has an unusual supply of “hidden value”

This is where Singapore’s market structure becomes particularly interesting.

The local market contains numerous companies with substantial property holdings, investment portfolios, subsidiaries and strategic assets that may not be fully reflected in their operating businesses.

Property groups are the obvious example.

A developer may own commercial buildings, hotels, residential development rights and stakes in listed companies.

The market may assign a relatively modest valuation to the overall group because investors are focused on weak property sentiment or slow earnings growth.

If management sells a non-core asset at an attractive price, redevelops a site or restructures the portfolio, the underlying value can become visible.

That is the essence of value unlocking.

And it explains why companies such as UOL Group, City Developments, Jardine Matheson and Singtel can become interesting even if their businesses are not experiencing spectacular top-line growth.

The investment thesis is not necessarily:

“earnings will explode.”

It can instead be:

“the market is mispricing what the company already owns.”

Falling interest-rate pressure could revive an entire forgotten part of the market

The potential rotation is particularly interesting for REITs and property companies.

Higher-for-longer interest rates had created a difficult environment for many property-related stocks.

Higher financing costs reduce distributable income for REITs.

Higher bond yields make dividend-paying equities less attractive relative to risk-free assets.

And higher discount rates reduce the present value investors are willing to assign to long-duration assets.

If interest-rate expectations stabilise or move lower, those pressures can reverse.

This does not require an explosive economic recovery.

It simply requires the market to stop pricing in increasingly aggressive future rate increases.

That could produce multiple expansion before earnings meaningfully improve.

This is an important distinction.

A REIT does not necessarily need a huge increase in rental income for its share price to recover.

If investors become comfortable assigning a higher valuation multiple to its existing income stream, the stock can rerate.

That makes selected industrial and healthcare REITs potentially interesting beneficiaries.

But investors should be careful with the REIT rebound thesis

Lower rates do not automatically make every REIT attractive.

Investors should examine:

• debt maturity schedules;
• refinancing costs;
• interest coverage;
• gearing;
• occupancy;
• rental reversions;
• asset valuations;
• and distribution sustainability.

A heavily leveraged REIT may gain from lower rates but still face structural problems with its assets.

The best candidates are likely to be REITs where the balance sheet is already manageable and falling rates simply unlock additional valuation upside.

That distinction separates a genuine recovery candidate from a value trap.

The EQDP could create a second wave of market participation

One of the less obvious developments investors should watch is Singapore’s Equities Market Development Programme.

With billions of dollars allocated or pending for the programme, the potential significance extends beyond the immediate recipients.

The broader objective is to make Singapore’s equity market more attractive and liquid, particularly for small and mid-cap companies.

That matters because the weakest part of Singapore’s equity market has historically been its limited depth.

Large companies can attract institutional capital.

Smaller companies often struggle with liquidity, analyst coverage and investor attention even when their underlying businesses are sound.

If institutional participation increases, the valuation gap between large and smaller companies could narrow.

That would create an interesting market-structure trade.

Investors do not necessarily need every EQDP beneficiary to become a great business.

They need some previously ignored companies to receive enough attention for valuation multiples to normalise.

Why small and mid-caps could outperform without becoming growth stocks

This is one of the most important implications of the potential rotation.

Small-cap investing is often associated with finding the next high-growth company.

That is not necessarily what is happening here.

A small company can generate strong investment returns simply because it is under-owned and under-valued.

Suppose a business is already profitable, has a healthy balance sheet and trades at a significant discount to comparable companies.

It does not need to double earnings.

It may simply need investors to recognise that its existing earnings deserve a higher multiple.

That is why the combination of:

cheap valuation + improving earnings + catalyst

can be particularly powerful.

The catalyst brings investors to the stock.

The valuation provides the potential rerating.

The earnings provide fundamental support.

The market may be entering a stock-pickers’ phase

This could be the most important change for Singapore investors.

During a broad market rally, simply owning the index or dominant banks can work.

During a rotational market, returns become much more dependent on individual catalysts.

Investors need to identify:

• companies whose assets are undervalued;
• businesses with earnings inflection points;
• stocks benefiting from structural government initiatives;
• REITs with potential multiple recovery;
• and mid-caps where institutional ownership could increase.

This is harder than buying the three major banks.

But it can also create greater opportunities.

The irony is that the market becoming more difficult may actually make it more rewarding for investors willing to do fundamental research.

Bull case: the rally broadens rather than collapses

The most constructive scenario is not a crash in bank stocks.

It is a rotation.

Investors continue holding profitable banks but redirect new capital toward lagging sectors.

Interest rates stabilise.

REIT valuations recover.

Property companies unlock assets.

EQDP-related capital improves liquidity.

Small and mid-caps receive greater institutional attention.

Corporate earnings become more important than macro speculation.

In this scenario, the STI can continue rising even if banks stop leading it.

That would actually be healthier for the market.

A rally supported by a wider group of companies is generally more sustainable than one increasingly dependent on three stocks.

Bear case: the market rotates because the rally is ending

There is another possibility.

Investors may not be rotating from banks because alternatives are becoming more attractive.

They may be rotating because they believe the entire Singapore market has become expensive.

If banks correct sharply, their enormous index weights could pull the STI lower.

And if investors simultaneously lose confidence in property, REITs and small caps, the supposedly attractive laggards could fall alongside the leaders.

There is also a risk that the anticipated catalysts fail to materialise.

Asset values can remain trapped inside conglomerates for years.

Government programmes do not automatically create shareholder returns.

And a lower-rate environment does not eliminate weak business fundamentals.

That is why “cheap” should never be confused with “undervalued”.

AI may actually strengthen the case for looking beyond AI stocks

The report’s caution on technology stocks is particularly interesting.

AI is unquestionably a structural trend.

But investors are increasingly asking a harder question:

Where is the money?

AI-related companies with extraordinary valuations need extraordinary earnings growth.

That raises the bar.

Meanwhile, companies outside the technology sector can potentially benefit from AI without being valued as AI companies.

A logistics company that improves route optimisation.

A bank that increases relationship-manager productivity.

A manufacturer that automates processes.

A property company that improves asset management.

A healthcare operator that improves scheduling.

These businesses can capture productivity benefits without requiring investors to pay technology-sector multiples.

This creates a potentially underappreciated theme:

AI beneficiaries do not necessarily have to be AI stocks.

Three types of stocks could benefit most from the rotation

Rather than attempting to predict the next sector winner, investors can think in terms of three investment categories.

1. Asset-rich companies

These are businesses where the market may be undervaluing property, investments or subsidiaries.

The catalyst is value realisation.

2. Capital-market beneficiaries

These include companies positioned to benefit from greater institutional interest and liquidity in Singapore’s small and mid-cap market.

The catalyst is increased investor participation.

3. Earnings catch-up stocks

These are companies where earnings are improving after being ignored during the bank-led rally.

The catalyst is fundamental earnings momentum.

The strongest opportunities may combine all three.

What investors should watch in the next 12–24 months

Bank valuations

The question is whether earnings can catch up with the substantial share-price gains.

Dividend support

Once major banks trade ex-dividend, their income appeal can temporarily weaken, making relative valuation more important.

Interest-rate expectations

A stabilisation in rates could be particularly beneficial for REITs and property stocks.

Asset monetisation

Watch for disposals, restructurings, redevelopment announcements and special distributions.

EQDP implementation

The actual deployment of capital matters more than the headline size of the programme.

Earnings revisions

The next market leaders are likely to be companies where analysts start raising earnings expectations.

Liquidity

Small-cap rerating stories need buyers.

Improving trading liquidity could therefore be an important catalyst in its own right.

So, should investors sell Singapore banks and buy value stocks?

Not necessarily.

That would be an overly simplistic interpretation.

DBS, OCBC and UOB remain high-quality financial institutions with strong franchises and attractive long-term economics.

The issue is marginal capital allocation.

After a major rally, the expected return from putting another dollar into an expensive bank stock may be lower than the expected return from buying an overlooked company with a clear catalyst.

That is the distinction investors should focus on.

Singapore’s next market opportunity may therefore not come from finding the next company capable of replacing the banks as index leaders.

It may come from finding companies that do not need to become the next banks to outperform.

A property company that unlocks hidden assets.

A REIT that benefits from falling financing costs.

A mid-cap manufacturer that attracts institutional capital.

A company whose earnings recover while its valuation remains depressed.

Those are potentially asymmetric situations.

The broader investment conclusion is therefore not “avoid Singapore banks.”

It is “look beyond them.”

After a period in which bank stocks have dominated the STI, the market may be entering a more selective phase in which earnings growth, asset value and identifiable catalysts matter more than simply owning the biggest companies.

For investors over the next 12–24 months, the opportunity may lie precisely where the index has not been looking.

The next leg of Singapore’s equity-market rally, if it comes, may be less about the banks getting bigger — and more about the rest of the market finally getting noticed.
